Why It Matters
States across the nation are burning through their financial cushions as tax revenues fall short and spending climbs. Idaho, which typically maintains stronger reserves than many states, could face pressure to cut services or raise taxes if its rainy day fund follows the national downward trend during economic uncertainty.
What Happened
State reserve funds declined nationally in fiscal year 2025 for the first time since the Great Recession, according to a new analysis from The Pew Charitable Trusts. The median state can now fund its operations for 47.8 days using reserve money, down from a record 54.5 days in fiscal 2024.
States collectively held $174 billion in savings last fiscal year, but 26 states saw their rainy day fund capacity shrink. In 14 of those states, lawmakers drew directly on reserves to cover expenses. Another 10 states grew their balances but at a slower pace than spending increased.
The decline follows years of stronger reserves bolstered by federal pandemic aid and higher-than-expected tax collections. Now states face increased costs, lower tax revenue, and federal budget cuts that are straining their finances.
By The Numbers
Wyoming maintained the strongest position with enough cash to operate for 320 days. New Jersey ranked last with reserves insufficient to cover even one day of state operations. Washington, Illinois, Delaware and Rhode Island also held minimal reserves compared to their spending levels.
Researchers examined data from the National Association of State Budget Officers to calculate how many days each state could fund its operations using only reserve funds. The analysis treats state reserves like household savings accounts that provide a cushion during disrupted tax revenues or economic downturns.
Zoom Out
State rainy day funds serve as a critical buffer against revenue shortfalls and unexpected expenses. Lower reserves mean states face quicker decisions about cutting services or raising taxes when budgets tighten. Many states now confront structural imbalances where revenue streams fail to keep pace with government spending.
Mountain West states, including Idaho, have historically maintained more conservative fiscal policies and stronger reserve positions than coastal states. The national trend toward depleted reserves signals broader economic pressures that could test even fiscally conservative states in the coming years.
What’s Next
Reserves provide short-term relief during fiscal stress but do not solve persistent budget imbalances. States will need to address structural spending issues as reserve funds continue declining. Lawmakers face difficult choices between reducing services, finding new revenue sources, or restructuring government operations to match available resources.
